Title:
ELECTRONIC DEVICE AND SYSTEM FOR LOCATION INFERENCE
Document Type and Number:
WIPO Patent Application WO/2023/191333
Kind Code:
A1
Abstract:
The present disclosure relates to an electronic device and a system for location inference. An electronic device, according to an embodiment of the present disclosure, comprises: a speaker that outputs an inaudible sound signal; at least one microphone that receives a first reflected wave signal in which the inaudible acoustic signal is reflected by a spatial structure; a memory that stores one or more instructions; and at least one processor that executes the one or more instructions, wherein the at least one processor executes the one or more instructions configured to: obtain a signal variation on the basis of correlation between a reference signal corresponding to the inaudible acoustic signal and the first reflected wave signal; when the signal variation exceeds a first threshold value corresponding to the motion of an object, obtain object location information corresponding to the location of the object in the spatial structure on the basis of the signal variation; and, when the signal variation exceeds a second threshold value corresponding to a change in the spatial structure, update a final parameter set corresponding to the inaudible acoustic signal by using a waveform optimization model.
